fix eye reflections

[Jamie]

While it was a fun idea to put the golang website in the eye's reflection, it doesn't quite work and needs to go. Perhaps might try finding or modelling a monitor to stick the emissive texture on, but probably best to go without and opt for a cleaner composition.

I really liked the golang.org reflection and I can't see why it didn't work... Could you bring it back? I liked way more then the current version.
